Enzymeless multi-sugar fuel cells with high power output based on 3D graphene–Co3O4 hybrid electrodes
Biofuel cells (BFCs), which use enzymes as catalysts to harvest energy from green and sustainable fuels abundantly producible from biological systems, are promising next-generation energy devices. However, the poor stability ...
2D single- or double-layered vanadium oxide nanosheet assembled 3D microflowers: controlled synthesis, growth mechanism, and applications
A facile one-pot solvent-thermal method was developed to synthesize a unique 3D microflower structure assembled from single- or double-layered 2D nanosheets of V4O9 (F-VO). Simply by controlling the precursor concentration, ...
Gallium-Doped Tin Oxide Nano-Cuboids for Improved Dye Sensitized Solar Cell
Tin dioxide (SnO2) is a potential candidate to replace conventional titanium dioxide (TiO2) in dye-sensitized solar cells (DSSCs) because of its wider bandgap and higher electron mobility. However, SnO2 suffers from low ...
Control of adipogenesis by the autocrine interplays between angiotensin 1–7/mas receptor and angiotensin II/AT1 receptor signaling pathways
Angiotensin II (AngII), a peptide hormone released by adipocytes, can be catabolized by adipose angiotensin-converting enzyme 2 (ACE2) to form Ang(1-7). Co-expression of AngII receptors (AT1 and AT2) and Ang(1-7) receptors ...
Graphene quantum dots as universal fluorophores and their use in revealing regulated trafficking of insulin receptors in adipocytes
Graphene quantum dots (GQDs) hold great promise as a new class of fluorophores for bioimaging, owing to their remarkable physicochemical properties including tunable photoluminescence, excellent photostability, and ...
High-strength carbon nanotube buckypaper composites as applied to free-standing electrodes for supercapacitors
Buckypaper is an attractive candidate material for free-standing electrodes in supercapacitors due to its high electrochemical performance, light weight, and thin dimensions. At present, however, free-standing buckypapers ...
A hierarchically structured composite of Mn3O4/3D graphene foam for flexible nonenzymatic biosensors
We report a novel composite material of hierarchically structured Mn3O4 grown on three-dimensional graphene foam (3DGF). This hierarchical Mn3O4/3DGF composite was fabricated as a flexible and freestanding biosensor for ...
The electrical detection of lead ions using gold-nanoparticle- and DNAzyme-functionalized graphene device
An electronic Pb2+ sensor, with high sensitivity and specificity, was developed based on DNAzyme- and gold-nanoparticle-functionalized graphene transistor.
Nanoporous tin oxide photoelectrode prepared by electrochemical anodization in aqueous ammonia to improve performance of dye sensitized solar cell
In this work, a nanoporous thin film consisting of sieve-like tin oxide (SnO2) sheets was prepared by anodization of tin foil in aqueous ammonia and applied as a photoelectrode for dye-sensitized solar cell (DSSC). Compared ...
Memory devices using a mixture of MoS2 and graphene oxide as the active layer
A mixed film consisting of 2D MoS2 and graphene oxide (GO) nanosheets is used to fabricate memory devices. The conductive MoS2 component in the MoS2-GO film increases the film conductivity, thus facilitating oxygen migration ...
